Specification of Iletters l'ratent. Patented. Sept. 15, 1914.

Application filed August 2, 1M3. Serial No.782-,680.

To all whom it may concern:

Be it known that 1, MAX M. Koor-I, citizen ofthe Unitel States, residing at Cleveland, in the county of Guyahoga and State. of

Ohio, have invented new and useful lmprovein'ents in @VQH-BTELCGS, of which the following is a specification.

. My present invention pertains to braces for the top and bottom walls of the ovens of steel-plate cooking ranges.

The said top and bottom walls in ranges of the kind stated are formed of sheet-steel; and one of the objects of my present invention' is to provide arigid brace for each wall, the said brace being ofop-en-work construction and extendingthroughout the area of the wall and being ribbed or arched and rigidly connected at frequent intervals to the wall in such manner as to absolutely preclude warping of the wall, and this without interfering in appreciable measure with the heat conducting and radiating quality of the wall. 1 Another object of the invention is to so construct the brace complementary to the bottom wall of the oven that said brace is adapted to hold and is also adapted for the, strong connection of the flue strip usually employed in the flue below the bottom wall of the oven.

Other advantageous characteristics of the invention will be fully understood from the following description and claims when the same are read in connectionwith the drawings, accompanying and forming part of this specification, in which: f

Figure 1 is an inverted plan showing my. novel brace as applied and connected the underside of the top steel plate or wall of an oven. 2 is a section. taken in the plane indicated by the line 2 9. of Fig. 1, and showing the ribbed or arched character of some of the bars of the brace. Fig. 3 is a detail vertical section taken in the plane indicated by the line 33 of Fig. 4:. Fig. 4-

2. Arr anged against the underside of the top plate or wall is my novel open-work bed or arched, as indicated by 7 with a view to increasing the stiffness and strength of the brace and enabling it to lend rigidity to the plate 1 andeffectually prevent Warping thereof. It will also be observed that at frequent intervals throughout its areafthe brace is provided. with apertures 8. These apertures are registered with countersunk apertures 9 in the plate 1 and are designed for reception of connecting bolts 10, the heads of the bolts being disposed in the countersunk apertures of the plates While the nuts complementary to the bolts are arranged against the flat portions 11 of the brace. At this point I would have it distinctly understood that while I prefer to fasten the'brace close against the underside of the plate 1 through the medium of bolts and nuts, I do not desire to be understood as confining myself to such specific mode of connection inasmuch 1 as the brace may be riveted to the plate 1 without departure from my claimed invention. At 12 the brace is provided with depending apertured end portions, and these are bolted or otherwise fixedly connected to the downwardly bent portions of the plate 1. This is advantageous inasmuch as it enables the brace to hold the said downwardly bent portions and tie the same to the horizontal major portion of the plate, and also because it enables the brace to hold the major portion of the plate down. It will further be observed thatat its forward end the brace is adapted as indicated by 13 for its proper fastening in connection with the front oven door plate (not shown) of a range.

i It will be gathered from the foregoing that my novel brace applied and connected in the manner described is calculated to effectually prevent warping of the top plate it will also be gathered that the brace is inexpensive and is therefore, not likely to materially increasethe cost of a range.

In Figs. 3 to 5, 1 is the bottom wall'or plate of an oven; and it is to be understood :that when said wall or plate is incorporated in a range it is disposed above. and spaced' from the, bottom wall of the range, thereby forming a flue below the oven. It is also to be understood'that 1 1 and 15, are the front and back downwardly bent portions of'the, plate or'wa'll; 16, the upwardly bent portion of the plate or wall adjacent the uptake flue of a range; and 17, the downwardly bent portion of the plate or wall adjacent the fire box of the range.

The brace shown in Figs. 8

shown in Figs. 1 and 2 and is applied and connected in similar manner to the underside of the oven bottom plate or wall 1 It will also be noted that the brace of Figs. 3 to 5 hasdepending portions 21 bolted or otherwise connected to the downwardly bent portions '14, and ,1? ofplate'l and that said brace also has upwardly, directed portions 22 bolted or otherwise connected to the up wardly bent portion 16 of the plate or wall l The brace shown in Figs. 3to further differs from that shown in Figs. 1 to-3 in the respect that it is provided in the back portion of one of its cross bars with a groove or channel 23. The said groove or channel 23 isto receive and hold the upper edge of a flue strip 2 1 which is connected at 25 to the plate or wall 1 and its complementary.

brace.

It will be readily notedfrom the foregoing that the brace shown in Figs. 3 to 5 is adapted to serve the same purpose with respect. to the plate or wall 1* that the brace Copies of this patent may be obtained for brace shown'in Figs. 3 to 5 is possessed of all or" the practical advantagesascribed to the brace of Figs. 1 and 2.

l. The combination ofva sheet-metal oven: plate having bent portions, and a rlgld brace arranged against the plate and having bars arranged at angles toeach other and spaces between the bars, and also havingdownwardly arched ribs on the bars and angularly disposed end portions on the bars, arranged. against and connected .to the bent portions of the ovenplate; the arched ribs on the bars being spaced apart and the pertions of the bars between the ribs being conout the area thereof.

The combination of a sheet-metal oven plate having bent portions, a rigid brace arranged against the plate and having bars arranged at angles to each, other and; spaces between the bars and also having downwardly nected to the oven plate at intervals throughto 5 is gener-- ally similar in construction to the bracearched ribs onthe bars, and angnlarly disposed end portions on the bars, arranged against and connected to the bent-portions of the oven plate, and 'fur ther having a channeled portion; the arched ribs on the bars being spaced apart and the portions of v the bars between the ribs-being connected to the oven plate at intervals throughout the area thereof, a fine strip the edge of which is disposed in said channeled portion, and

means connecting said strip with the oven plate and the brace.
